5 ISLAND.

To all whom it may concern Be it known that I, RALPH K. MAKER, a citizenof the United States, and resident of the city of Providence, in thecounty of Providence andState of Rhode Island, have invented certain newand useful Improvements in Safety-Catches for Pins, of whichthefollowing a specification.

This invention relates to safety catches and has for its object toprovide a keeper having two safety catch'comprising a hook shaped sideears mtegral with and bent up from a common base, the inner surface ofsaid ears having duplicate registering annular grooves in which aslotted sub' stant-ially ring-shaped guard member is movably mounted,said member being provided with an operating handle projecting outwardtherefrom beyond the periphery of the keeper whereby said member may bemoved to bring its opening into and out of register with that of saidkeeper.

A further object of said invention is to form one end of said member'out of line with said slot whereby it is sprung back into linetherewith upon entering said groove to retain said member in position inthe groove-by friction.

'With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claims.

Of the accompanying drawings: Figure 1 is a side elevation of myimproved safety catch retaining the point of an ordinary pin-stem, theopposite end of the stem being securedto the pin body by a joint in theusual Way. Fig. 2- is a view of the inner face of the keeper as blankedfrom the stock showing the hook shaped opening in the ears and theannular registering grooves in which theguard member is,

by it is sprung inward in entering the groove to retain said member in"position therein by friction. y

Referring to the drawing 1 designates the usual pin stem mounted at oneend in the Joint member 2 attached to the body portion 3. My improvedsafety catch member 1 may be formed integral with or made separate andattached to the opposite end of the pin body to receive the pointedendof the pin stem, said catch member being constructed of two members,one the keeper 5 and the other the guard 13. In forming the keeper 1t ispreferably blanked out of sheet stock into the shape illustrated in Fig.2 having a pair of enlarged ears or members 6-(3 joined together by theconnector or base portion 7 from which the ears are bent up into opera.tive position, which base provides the necessary portion by which thekeeper may be attached to the pin body. Each of these ears is providedwith an opening 8 formed inward to the center 9 from the margin thereofnear the base whereby each ear is made in substantially a hook form, theinner surface of each ear being provided with an annular groove 10around the center opening, being adapted to register when the ears arebrought together. A port-ion of the stock at 11 at the back of the hookre moved forming a slot 12, see Fig. 7, communicating with the groove10.

The guard member 13 is made in substantially a ring shape having amarginal opening 14 and an operating handle 15 nearly opposite saidopening. The end 16 of this guard member is thrown outward slightly outof line with the rest of the ring and with the groove 10 so that whenthis guard member is placed in the "annular groove and the joint earspressed together thereover the ring may be moved back and forth so as tocause its opening 14 to be moved into and out of line with that of theopening 8 in said ears, the offset portion 16 of said member being forthe purpose of creating a sufficientamount of friction of the. ring inits groove to hold the guard men'iber in its closed or locked position.

in assembling the parts the keeper is blanked out into the formillustrated in Fig. 2,then bent up into that illustrated in Fig. 3 whenthe guard member is placed into position within the grooves and the earsfinally closed tightly together in which position .from a common base,

they are retained by the stock at the base I portion 7.

- In operating, to open the catch it is only necessary to move thehandle up against the stop or end wall 17 and to lock the same to movethe handle down against the end wall 18 of the grooi e 12. By thisarrangement the operating handle is out of the way and practically outof sight when the catch is in locked or operating position.

1. In a safety catch, a keeper having a pair of side ears, integral withand bent up each of said ears being provided with a hook-shapedpintongue receiving opening formed inward to its center from the marginthereof, the inner face of each ear being provided with an annulargroove about said center opening each registering with the other, aportion of the stock at the backpf the hook'adjacent said groove beingremoved forming a slot communicating with said groove, a ringshapedguard member having a marginal opening and slidably mounted in saidgroove, and a handle on said guard extending through said slot wherebysaid ring may be moved to bring its opening into and out of line withthat of said keeper.

2. In a safety catch, a keeper having a pair of side ears integral withand bent up from a common base, each of said ears being provided with ahook-shaped pintongue receiving opening formed inward to its center fromthe margin thereof, the inner face of each ear bein provided with anannular groove about said center opening each registering with theother, a portion of the stock at the back of the hook being removedforming a slot communicating. with said groove. a rin shaped guardmember having a marginal o Sening and slidably mounted in said groove,and a handle on said ring extending through said slot whereby said ringmay be moved to bring its opening into and out of line with that of saidkeeper, one end of said guard member being offset slightly out of linewith sprung inward upon entering the groove to retain said member inposition therein by friction.
